Beschreibung
Zusammenfassung:	An additive fabrication apparatus is provided comprising a movable foil guiding stage (180) having a contact face (181) and comprising on opposite sides of the contact face a pair of upper and lower foil guiding elements (190, 191), the lower foil guiding element (190) defining a foil height position (H0) distanced from the contact face (181), for guiding a foil (6) including a liquid layer (30) to or from the contact face to contact a tangible object (50) by movement of the foil guiding stage along the tangible object while keeping the foil stationary relative to the object (50). An energy source (90) is arranged for at least partially solidifying at least part of an intersection pattern in the liquid layer arranged on the foil and in contact with the tangible object.
